Technical Field

[0001] The utility model belongs to the technical field of slitting equipment, and more specifically, particularly relates to a PE plastic bag slitting equipment. Background Art

[0002] In the production process of PE plastic bags, it is necessary to cut a larger raw material into several small strips. In the next step, the so-called cutting is to divide the larger raw material into several small strips, and the PE plastic bag cutting equipment is to cut the entire PE plastic bag into several small strips.

[0003] For example, a Chinese patent with publication number CN218876449U discloses a PE plastic bag slitting device, including a bottom plate, a vertical plate 1 and a vertical plate 2 are fixedly connected to the top of the bottom plate, the vertical plate 1 and the vertical plate 2 are symmetrically distributed on both sides of the bottom plate, the side of the vertical plate 1 is fixedly connected to the second motor and the third motor, the output end of the third motor is detachably connected to the collecting rod 2 through the coupling 1, the output end of the second motor is detachably connected to the collecting rod 1 through the coupling 2, the side of the vertical plate 2 away from the first motor is movably connected to the sleeve through a spring, and the collecting rod 1 and the collecting rod 2 are both arranged between the vertical plate 1 and the vertical plate 2. The utility model is provided with a spring and a sleeve, when the collecting rod 1 and the collecting rod 2 collect a certain amount of PE plastic bags, the collecting rod 1 and the collecting rod 2 can be removed from the slitting device by pressing the sleeve, and then a new collecting rod can be placed on the slitting device, so that the working efficiency of the PE plastic bag slitting device is further improved;

[0004] The technical solution recorded in this proposal is to set a sleeve, and when the sleeve is pressed, the collecting rod can be removed from the slitting device. However, during actual use, when the cutting edge is worn out after long-term use, the cutting edge on the slitting device needs to be replaced. However, in this solution, the cutting edge is fixedly connected to the circumferential surface of the cutting rod, which makes it inconvenient to replace the cutting edge, thereby reducing the practicability of the slitting device.

By setting the first spring 1005, it is convenient to realize the resetting of the insertion rod 1007 and the movable plate 1006 under the action of the elastic force of the first spring 1005.

[0032] The specific usage and function of this embodiment are as follows:

[0033] When using this product, first check whether the internal mechanisms of the PE plastic bag slitting equipment are complete. After ensuring that they are complete, when it is necessary to replace the cutter 2007 on the slitting equipment, start the motor 2016 to rotate the bidirectional screw rod 2015, so that the moving block 2014 connected to its external thread and the moving block 2014 slidably connected to another mounting frame 2013 drive the moving seat 2001 to move in opposite directions, thereby taking out the cross bar 2002 inserted between the pair of moving seats 2001, pulling the pull rod 2010 to drive the pressing block 2012 to move to the end away from the insert block 2008, so that the pressing block 201 2 is moved out from between the pair of insert blocks 2008, so that the pair of insert blocks 2008 are contracted to the inside of the mounting block 2005 under the elastic force of the second spring 2009, and then the mounting block 2005 is pulled outward to separate the strong magnet 2004 at the joint of the mounting block 2005 and the placement frame 2003, thereby realizing the removal of the cutter 2007 on the cross bar 2002, which is convenient for the subsequent replacement of the cutter 2007.
